THE UTILIZATION OF SYNTHESIZED COHERENCE FUNCTION IN OPTICAL TIME-DOMAIN REFLECTOMETRY
The paper deals with the synthesis of an optical coherence function and its application in Optical Time-Domain
Reflectometry (OTDR). A brief summary of up-to-date approaches to the optical reflectometry is given. The fundamental
equation of Optical Coherence-Domain Reflectometry with Synthesized Coherence Function (OCDR-SCF) is derived and a general
theoretical approach to the synthesis of a coherence function of arbitrary shape is outlined. The obtained results are
illustrated on the synthesis of three different shapes of coherence function. The main performance parameters of the
OCDR-SCF and the most significant advantages and drawbacks of this approach are discussed.
